agg demand¨


Aggregate demand
The total spending on goods and services in  a period of time at a given price level

Consumption
The total spending by consumers on domestic goods and services
Durable and non durable

Investment
The addition of capital stock to the economy
Replacement investmant
Induced investment

Government spending
Depends on policies

Net export
Goods and servcices bought and sold by foriegners


Changes in the components of aggregate demand
Changes in income

Changes in interest rates
If interest rates change there is less borrowing and consumption will fall
If interest rates fall people will borrow more

Changes in wealth
Made up of the assets peopkle own
2 main  factors for wealth

A change in the housing market
A change in the stocks and shares

Changes in consumer confidence
If people ar optimistic about the future they will spend more

Household indeptness
The extents to which households are willing and able to borrow money affect consumption. If interest rates are low and it is easy to borrow and spend increasing AD. If interest rates rise household will have to spend more to re-pay their loans and mortgages and spending will drop.

What causes changes in investment
Interest rates
People will borrow money
Changes in national income
As national ncome rises more demand then more investments into new plants
Tech changes
Expextations
Planning for the future
What causes changes in gov spending
Based on policy
What casuses changes in net export
What causes changes in Net Exports?
1
Changes in domestic national income-


An increase in Y puts pressure to decrease
2
Changes in foreign income-

When foreign incomes rise rightward preasrure is placed on AD because foreigners buy exports.


3
Relative currency values-
If domestic currency has a high value leftward pressure is placed on AD because to foreigners goods/services seem expensive.

4
Trade policies
Protectionist policies put leftward pressure on AD whereas free-trade policies place rightward pressure on AD.

5
Relative inflation rates among trading partners


Hight inflation rates make goods seem expensive to foreigners.


Fiscal policy
Fiscal policy- the set of governments policies relating to its spending and taxation rate.
Direct taxes-taxes on income
Indirect taxes- taxes on goods and services
Money supply= refers to the amount of money in circulation at a given period of time
Interest rate= Base rate/discount rate/prime rate-the price charged to borrow money. The rate charged by the central bank to other banks

Expansionary fiscal policy
(Encourage consumption-shift AD right)
Lower income tax to increase disposable income
Lower corporate taxes to encourage investment
Increase government spending to improve or increase public services


Contractionary fiscal policy
(Discourage consumption-shift AD left)
Raise corporate taxes
Decrease government spending


Monetarty polic
The set of official policies governing the supply of money in the economy and the level of interst rates in an economy

Expansionary monetary policy
Decrease the interest rate
Increase the money supply
Decrease the reserve ratio
Buy back governments bonds

Contractionary monetary policy
Increase the interest rate
Decrease the money supply
Increase the reserve rate
Sell gov bonds.




S 14 aggregate demand work sheet


S14: Aggregate Demand
Objective 1: Distinguish between demand and aggregate demand (AD).
Define demand-
the willingness and ability to buy a product at a given time.
Define aggregate demand-        
Total spending on goods and services in a period of time at a given price level.
 Microeconomic demand curve                         Macroeconomic demand curve

                                                GDP price deflator                                                      AD
           Quantity                                          Real output=real gdp=national income=y
Objective 2: Define and describe the components of aggregate demand. *think GDP expenditure approach here.

Consumption

The total spending by consumers on domestic goods and services


·         Durable Goods-any good that’s going to be consumed over a period of time.

·         Non-Durable Goods- are goods such as rice, toilet paper and newspapers that are used immediately or in a relatively short period of time.


Investment

Defined as the addition if capita stock. Investment is carried out by the firms and there are two types: 1. Replacement investment- firms spending to maintain the productivity if their existing capital.
2. induced investment occurs when firms spend on capital to increase their output to respond to higher demand in the economy.

·         Capital Stock- includes all goods that are made by people and are used to produce other goods or services such as factories, machines, offices or computers.


Government spending

Governments at a variety of levels (federal, state/provincial) spend on a wide variety of goods and services; health, education, law and order, transport, social security, housing and defence.
Depends on gov. policies.


Net exports (X-M)

Export revenues minus import expenditures (the figure can be either positive (when revenues exceed expenditure) or negative (when expenditure exceeds revenues))
If net exports is pistive it will add to AD, if it is negative, it will reduce AD


Objective 3- Explain the determinants of the components of AD.
What causes changes in Consumption?
1
Changes in income-

When national income goes up, aggregate demand goes up.



2
Changes in interest rates-

When interests rates goes up, aggregate demand goes down


3
Changes in wealth-

An increase in wealth results in a rightward shift of the AD curve

Wealth goes up demand up

4
Changes in expectations /consumer confidence-

Optimism about the economic future results in more spending now: ogton measure by consumer confidence index


5
Household indebtedness-
The extents to which households are willing and able to borrow money affect consumption. If interest rates are low and it is easy to borrow and spend increasing AD. If interest rates rise household will have to spend more to re-pay their loans and mortgages and spending will drop.


What causes changes in Investment?
1
Changes in Interest Rates

When it goes u demand goes down



2
Changes in level of National Income
If it goes up demand goes up

3
Technological Changes
When it goes up demand goes up

4
Changes in expectations /business confidence-
When it goes up demand goes up





What causes changes in Government Spending?
1
Changes in policy-

Dependent on policy




What causes changes in Net Exports?
1
Changes in domestic national income-


An increase in Y puts pressure to decrease
2
Changes in foreign income-

When foreign incomes rise rightward preasrure is placed on AD because foreigners buy exports.


3
Relative currency values-
If domestic currency has a high value leftward pressure is placed on AD because to foreigners goods/services seem expensive.

4
Trade policies
Protectionist policies put leftward pressure on AD whereas free-trade policies place rightward pressure on AD.

5
Relative inflation rates among trading partners


Hight inflation rates make goods seem expensive to foreigners.

Objective 7: Explain how governments can use monetary and fiscal policy to alter the level of AD in an economy.

Fiscal policy- the set of governments policies relating to its spending and taxation rate.
Direct taxes-taxes on income
Indirect taxes- taxes on goods and services
Money supply= refers to the amount of money in circulation at a given period of time
Interest rate= Base rate/discount rate/prime rate-the price charged to borrow money. The rate charged by the central bank to other banks

Expansionary fiscal policy
(Encourage consumption-shift AD right)
Lower income tax to increase disposable income
Lower corporate taxes to encourage investment
Increase government spending to improve or increase public services

Contractionary fiscal policy
(Discourage consumption-shift AD left)
Raise corporate taxes
Decrease government spending

Expansionary monetary policy
Decrease the interest rate
Increase the money supply
Decrease the reserve ratio
Buy back governments bonds

Contractionary monetary policy
Increase the interest rate
Decrease the money supply
Increase the reserve rate
Sell gov bonds.

Objective 8- Explain the Nature of a government budget
Government budget-refers to the total spending by all levels of government and is split into three categories
1.       Capital expenditure- includes spending that adds the capital stock of the economy, ie. Upfrading ahighway or school
2.       Current expenditure- on going spenind such as purchases of textbooks or wages to  publice sector employees
3.       Transfer payments-
Gov revenue comes from
Taxes- direct income
Tariffs- taxes on imported goods
Profits- or sales of nationalized businesses
Rent- of gov owned buildings or land
-          Governments lay out their national budgets yearly showing their expected revenues and expenditure this is called the fiscal stance
-          Budget surplus- when governments earns more than it spends
-          Budget deficit- when governments spends more than it earns
-          Balanced budget- when governments earning equal what they spend


To finance or run a budget deficit the government musr borrow money from
a)      Household
b)      Firms
c)       Foreign countries
-          To do this they sell gov bonds
-          People buy bonds as  as a form of saving; they lend money to the government and are eventually paid back along with extra payment
-          The national debt is the sum of budget deficits over time.

The Level of Overall Economic Activity Objectives Organizer

Define Macroeconomics:

Branch of economics that studies decision making for the economy as a whole, ie examining growth

Objective 1: List and explain the five main macroeconomic goals of an economy.

Economic growth

1. a steady rate of increase of national output

Employment

a low level of unemployment

Price stability

a low and stable rate of inflation

External stability

a favorable balance of payments position.

Income distribution

an equitable distribution of income

*The order here is quite logical, if it helps you remember.

Objective 2: Describe and illustrate the circular flow of income model of the economy for a closed (two-sector) economy and an open (four sector) economy with government and financial markets.

Closed (two-sector) micro circular flow model

Factor resource market

Product market

House holds

firms

expenditure

Goods and services

Rent, wages, interest profit

Land, labour, capital, etr


Open (four-sector) macro circular flow model

households

firms

expenditure

income

Investments

exports

Governments spending

Savings

imports

taxes


Notice/Know and understand the relationships!

Leakage Injection

Savings

Foregoing current consumption to allow future consumption

-|banks

Investment

An increase in capital stock by firms to expand output

-|borrow from banks

Imports

Spending on imports is a leakage

-|the money flows out of circulation to foreign firms

Exports

Foreigners spend money to buy domestic products thereby injecting money into an economy

Taxes

Taxes are paid to the government (taking that money out of circulation)

Subsidies

Government spending injects money into the circular, flow.

Define Transfer Payments-

A payment to an individual from the government that does not expect an increase in output

Important Conclusions:

· The economy is in equilibrium when:

LEAKAGES=INJECTIONS

· If leakages rise without a corresponding increase in injections:

THE NATIONAL OUTOUT WILL FALL, THERE WILL BE LESS INCOME CIRCULATING.

· If injections rise without a corresponding rise in leakages:

THERE WILL BE MORE MONEY IN CIRCULATION

Objective 3: Distinguish between the output approach, the income approach and the expenditure approach for measuring national income. [know the different ways GDP is calculated]

*The most common measure of a country’s national income is gross domestic product (GDP).

There are three methods to calculate GDP:

1

The output method

Measures the actual value of the goods and services produced (# 3 on circular flow)

Calculated by summing all the value added by all the firms in an economy (making sure not to double count by subtracting input cost)

Data usually grouped according to different production sectors: primary, (agriculture, mining), secondary (manufacturing), tertiary (services)

2

The income method

Measures the value of all the incomes earned economy (wages, rent, interest, profits) (#2 on circular flow)

3

The expenditure method

Measures the value of all spending on goods and services in the economy. –Calculated by summing spending by different sectors in the economy (c+i+g+x-m (number 4 of circular flow)

Consumption, investment, governments, net exports

National Output = National Income = National Expenditure

How accurate are these statistics? In theory they are always equal, is this really true? Why? Why not?

Presumably accurate depending how develpoe or underdeveloped the country may be

The data comes from may and varied sources so inevitably there are inaccucies leading to imbalances among the final values

Some inaccuracies are due to timing, some are due to collection

Objective 4: Define and distinguish between Gross Domestic Product (GDP) and Gross National Product (GNP)/ Gross National Income (GNI) as measures of economic activity.

GDP- The total value ofof all final goods+services produced in an economy in a given year measured by c+i+g+(x-m)

GDP- may be defines as the total value og all economic activity in a country regardless of who owns the productive assests

Ie. An Indian MNC operating within canadas borders and earning profit towards canadas GDP, not indias.

GNP/GNI-

Is the total income earned by a country’s factors of proudction regardless of where the assets are located?

Formula for GNP/GNI:

GNP= GDP + net property income from abroad (income earned by assets abroad minus income paid to foreign assets operating domestically)

GNI versus NNI: Net national product

NNI=GNI- depreciation of capital stock (capital consumption)

NNI takes into account the depracitate (loss of value) off capital or capital consumption due to:

Wear and tear as machinery is used

Damage to capital equipment

Absolute technology

Objective 5: Define and distinguish between total GDP & GNP/GNI and per capita GDP & GNP/GNI

Per capita:

Total gdp divided by the population

What does looking at per capita statistics allow for that looking at total statistics does not?

Comparison between countries

Objective 6: Define and distinguish between the nominal value of GDP and GNP/GNI and the real value of GDP and GNP/GNI.

Nominal: number (not adjusted for inflation)

real: Number adjusted for inflation (done using the gdp deflator)

Why are ‘real’ values of national income statistics more valuable than nominal values?

Objective 6: Explain the meaning and significance of “green GDP”

Green GDP= GDP-enviromental costs of production

Green GDP is a measure of GDP that ctakes into account any environmental costs incurred from the production of the coods and services included in the GDP figures

China calculated green GDP for 2004 + showed a 3% costs for pollution

Stopped calculating the next year due to arguments

India is discussing calculating green GDP accounts in 2015

Objective 7: Evaluate the uses of national income statistics.

Why are they gathered?

Act as a report growth been achived

Gov. uses stats to develop policies

Economist to stats to develop models and make forecasts

Business use stats to male forecasts about future demand

To measure performance of the economy over time (real)

As a starting point for measuring the welfare of a nations people

AS a base for comparing different countries

What are the limitations of national income statistics?

Inaccuracies

Dara used to calculate the measure comes from a variety of sources such as tax claims, output data and sales data.

Figures tend to become more accurate overtime (after a lag) as they are revised

Statisticians try to be as accurate as possible, and in more devoped countries

The UN SNA works to improve data

Hidden economy

Unrecorded or under recorded economic activity, informal market

-National income accounts only record information formally reported and officially recorded

They don’t include do it yourself work or work done at home

This is quite significan in devoping countries where much output does not get recorded

Also the hidden economic (black market)

Externral costs

Negative externalities of production

Life concerns

GDP ,amu grow because people are working longer hours or taking power holidays

Composition of output

Is it possible that a large part of a countries outpit is in goods that do not benefit consumers

-military equipment

- in this case it would be hard to argue a higher GPD will raise living standards

Objective 8: Explain and illustrate the business cycle and its phases.

Periodic fluctuations in economic activity measured by changes in real GDP

Demonstrates patterns seen in developed countries of periods of rising growth, followed by periods of slowing growth and even falling growth.


boom Recovery

recovery recession

trough


expansion contraction expansion

Long term trends and output gaps

Positive output gap-

the economy is producing above its trend- inflation is likely to be a problem.

Negative output gap-

gap- the economy is producing below its trend- unemployment is likely to be a problem


Objective 10: Calculate nominal GDP from national income data using the expenditure approach.

GDP = C + I + G + (X - M)


C = Household and personal consumption expenditures

I = Gross private domestic investment expenditures

G = Government consumption and gross investment expenditures

X = Expenditures on goods and services exported

M = Expenditures on goods and services imported
